Eaton, Cummins experts help author book on advanced hybrid technologies

More About:

Eaton Corp. scientist Dr. Haoran Hu along with Cummins Engine executive director of systems engineering Dr. Rudy Smaling have helped author a new book published by SAE International. The book, “Advanced Hybrid Powertrains for Commercial Vehicles,” was written with fellow author Simon Baseley, who recently retired from Bosch Rexroth Corp. and is now a visiting research investigator at the University of Michigan.

The 404-page book, which can be ordered here, details the latest trends and technologies in the rapidly developing hybrid commercial vehicle market.

The potential for significantly improved fuel economy, cleaner air, lower operating costs and less dependence on traditional fuel supplies are driving the market for hybrid powertrains, particularly in the transportation industry, Hu noted.

“Eaton already has achieved a 30% boost in fuel economy in tests with its electric-hybrid powertrain in the city bus driving cycle,” Hu said. And, he added, recent tests by the U.S. Environmental Protection Agency demonstrated the potential for a 50% improvement with hydraulic hybrid systems.

Next-generation technologies such as full-electric systems, fuel cells and the role hybrid commercial vehicles could play in future intelligent transportation systems also are detailed. Other chapters address government regulations and incentives as well as other market drivers and challenges.
